更改Yesod端口号 [英] Change Yesod port number

问题描述

从部署Yesod网络应用，我可以将可执行文件，并配置文件以运行Yesod作为独立的Web服务器。这是目录结构。

 ├──config 
│├──client_session_key.aes 
│├──favicon.ico 
│├──keter.yml 
│├──车型
│├──robots.txt 
│├──路线
│├──设置。 yml 
│├──sqlite.yml 
│└──test-settings.yml 
├──my-project 
├──my-project.sqlite3 
└──static 
  

我尝试通过更改config / settings.yml来使用不同的端口

  port：_env：PORT：3002
批注：_env：APPROOT：http：// localhost：3002
  

然而，应用仍然可以通过端口3000访问。即使我删除了settings.yml，但是没有错误信息。

更改端口的方法是将环境变量 export PORT = 3002 从 https://github.com/yesodweb/yesod/wiki/Configuration ＃overriding-configuration-values-with-environment-variables ，但我不是我可以使用的。

对于开发，我可以使用 stack exec - yesod devel -p 3003 （），但我似乎没有在Yesod可执行文件（my-project）中使用 -p 选项。

为什么可执行文件没有（似乎）加载 config / settings ？如何设置在Yesod网络应用程序中使用不同的端口？

解决方案

看起来设置文件应该与可执行文件位于同一目录中。

我复制当前目录中的config / settings.yml，然后运行 ./ my_project settings.yml ，现在它正确使用3002端口。

我从 https：/ /github.com/yesodweb/yesod/issues/474

From Deploying Yesod web app, I could copy the executable, static, and config file to run Yesod as a standalone web server. This is the directory structure.

├── config
│   ├── client_session_key.aes
│   ├── favicon.ico
│   ├── keter.yml
│   ├── models
│   ├── robots.txt
│   ├── routes
│   ├── settings.yml
│   ├── sqlite.yml
│   └── test-settings.yml
├── my-project
├── my-project.sqlite3
└── static

I tried to use different port by changing config/settings.yml

port:           "_env:PORT:3002"
approot:        "_env:APPROOT:http://localhost:3002"

However, the app is still accessible with port 3000. Even I removed the settings.yml, but there was no error message.

The way to change the port was from changing the environment variables export PORT=3002 from https://github.com/yesodweb/yesod/wiki/Configuration#overriding-configuration-values-with-environment-variables, but I it's not what I can use.

For development I can use stack exec -- yesod devel -p 3003 (how can I change the settings (e.g., port) used by "yesod devel"?), but I don't seem to use the -p option with the Yesod executable (my-project).

Why the executable does not (seem to) load config/settings? How to setup to use different port in Yesod web app?

解决方案

It looks like that the setting file should be in the same directory as the executable.

I copied config/settings.yml in current directory, then run the ./my_project settings.yml, now it uses the 3002 port correctly.

I have some hints from https://github.com/yesodweb/yesod/issues/474
